So I did a few assignments with my Nikon F90x and surprisingly... a lot of shots are out of focus. I'm using a manual focus 50mm F1.4 Ai lens so I use the electronic rangefinder and rely on it quite heavily since I shoot in lower light.
The thing is, I used it in spot AF mode (vs wide AF mode) most of the time and am wondering if this is potentially the cause of my AF woes? Or has anyone else experienced F90x's suffering from back/front focusing (even on the electronic rangefinder and manual focusing?).
